<p><strong><a name="rclientconf"></a>A5. Radiusclient Configuration for Fedora Core 4 / 5 / 6</strong><br>
(last update: 19 May 2007)</p>
<p>Radiusclient is required because the pppd radius plugin relies on it. There are a few configuration files in /etc/radiusclient to look at. The first one is /etc/radiusclient/servers which specify the radius server name and key. We have the radius server in the same box. So the file is like this:</p>
<blockquote>
  <pre>#Server Name or Client/Server pair              Key<br>#----------------                               ---------------<br>localhost                                       testing123	 </pre>
</blockquote>
<p>The key is the secret of the radius server which is specified in /etc/raddb/clients.conf. Older version of freeradius has the default key &quot;testing123&quot;. Of course, it is a bad idea to use the default.</p>
<hr>
<strong>A5.1 radiusclient.conf </strong><br>
(last update: 19 May 2007)
<p>The main configuration file for radiusclient is /etc/radiusclient/radiusclient.conf. Here is how it should be when all remarks are stripped off:</p>
<blockquote>
  <pre>auth_order radius
login_tries 4
login_timeout 60
nologin /etc/nologin
issue /etc/radiusclient/issue
authserver localhost
acctserver localhost
servers /etc/radiusclient/servers
dictionary /etc/radiusclient/dictionary
login_radius /usr/sbin/login.radius
seqfile /var/run/radius.seq
mapfile /etc/radiusclient/port-id-map
default_realm
radius_timeout 10
radius_retries 3</pre>
</blockquote>
<p>Basically, all of the lines are default. I have not changed anything.</p>
<hr>
<strong><a name="dict"></a>A5.2 dictionary.microsoft</strong><br>
(last update: 19 May 2007)</p>
<p>In /etc/radiusclient, there is a file called dictionary. Add the following line to the end of the file.</p>
<blockquote>
  <pre>INCLUDE /etc/radiusclient/dictionary.microsoft</pre>
</blockquote>
<p>The file, dictionary.microsoft, is not included in the radiusclient. We can modify the one from freeradius so that it can be used by pppd.</p>
<p>First of all, copy the freeradius one, /usr/share/freeradius/dictionary.microsoft, to /etc/radiusclient. Then change the word &quot;octets&quot; to &quot;string&quot; in the file. Add the word Microsoft to all attributes. Here is my version: </p>
